pycyclops

---

cyclops is a toolkit for facilitating research and deployment of ML models for healthcare. It provides a few high-level APIs namely:

• data - Create datasets for training, inference and evaluation. We use the popular 🤗 datasets to efficiently load and slice different modalities of data
• models - Use common model implementations using scikit-learn and PyTorch
• tasks - Use common ML task formulations such as binary classification or multi-label classification on tabular, time-series and image data
• evaluate - Evaluate models on clinical prediction tasks
• monitor - Detect dataset shift relevant for clinical use cases
• report - Create model report cards for clinical ML models

cyclops also provides example end-to-end use case implementations on clinical datasets such as

• NIH chest x-ray
• MIMIC-IV

🐣 Getting Started

Installing cyclops using pip

python3 -m pip install pycyclops

cyclops has many optional dependencies that are used for specific functionality. For example, the monai library is used for loading DICOM images to create datasets. Hence, monai can be installed using python3 -m pip install pycyclops[monai]. Specific sets of dependencies are listed below.

Dependency	pip extra	Notes
xgboost	xgboost	Allows use of XGBoost model
torch	torch	Allows use of PyTorch models
torchvision	torchvision	Allows use of Torchvision library
torchxrayvision	torchxrayvision	Uses TorchXRayVision library
monai	monai	Uses MONAI to load and transform images
alibi	alibi	Uses Alibi for additional explainability functionality
alibi-detect	alibi-detect	Uses Alibi Detect for dataset shift detection

🧑🏿‍💻 Developing

Using poetry

The development environment can be set up using poetry. Hence, make sure it is installed and then run:

python3 -m poetry install
source $(poetry env info --path)/bin/activate

In order to install dependencies for testing (codestyle, unit tests, integration tests), run:

python3 -m poetry install --with test

API documentation is built using Sphinx and can be locally built by:

python3 -m poetry install --with docs
cd docs
make html SPHINXOPTS="-D nbsphinx_allow_errors=True"

Contributing

Contributing to cyclops is welcomed. See Contributing for guidelines.

📚 Documentation

If you need to build the documentations locally, make sure to install Pandoc in addition to docs poetry group.

📓 Notebooks

To use jupyter notebooks, the python virtual environment can be installed and used inside an IPython kernel. After activating the virtual environment, run:

python3 -m ipykernel install --user --name <name_of_kernel>

Now, you can navigate to the notebook's Kernel tab and set it as <name_of_kernel>.
